The largest green roof in Indiana, at 79,096 square feet, has been installed on the University of Notre Dame’s Joyce Center, home to the Fighting Irish Athletics Department and the Purcell Pavilion arena.
Installation of green roofs is one strategy in the University’s Comprehensive Sustainability Strategy to cut its carbon footprint in half by 2030, which University President Rev. John I. Jenkins, C.S.C., announced in September 2015 in response to Pope Francis’ encyclical Laudato Si’.
The Joyce Center green roof is believed to be the largest at any U.S. college or university. Spanning nearly 2 acres of space along and between the double domes of the Joyce Center, the roof surface is the fifth living rooftop installed at Notre Dame. The University’s other greenscapes are atop the Morris Inn, Corbett Family Hall, Duncan Student Center and O’Neill Hall. At more than 122,000 square feet, the University’s total living roof system makes up the largest vegetative roofscape in Indiana.
“The University is firmly committed to being a good steward of our natural resources,” said John Affleck-Graves, executive vice president. “In addition to saving energy and improving stormwater runoff, this green roof will also contribute to the natural beauty of our campus while replicating the design of our quads.”
The Joyce Center green roof was designed and grown by LiveRoof from Spring Lake, Michigan, and installed by Midland Engineering Company of South Bend. In total, 32,798 trays of plants form the design. The layout consists of 25 plant species, including 22 varieties of sedum. A rooftop irrigation system also was installed.
